Abstract

The authors describe two methods to reduce the discontinuity of the image in coarse integral volumetric imaging. The discontinuity of elemental images from neighboring elemental lenses is smoothed by introducing Fresnel elemental lenses with interleaved grooves. The discontinuity of volumetric layers with long intervals is made indistinct by introducing a smoothing filter and an edge filter to connect the layered images smoothly. The effectiveness of the proposed methods is confirmed by the prototype systems.
